24、 methodology of conformance testing, ISO/IEC 9646-1 5, ISO/IEC 9646-2 6, ISO/IEC 9646-3 7 and ISO/IEC 9646-5 SI, as well as the ETSI rules for conformance testing, ETS 300 406 9 and ETR 141 lo are used as a basis for the test methodology. Annex A provides the Tree and Tabular Combined Notation (TTCN

25、) part of this ATS. Annex B provides the partial Protocol Implementation extra Information for Testing (PIXIT) Proforma of this ATS. Annex C provides the Protocol Conformance Test Report (PCTR) Proforma of this ATS. 2 References The following documents contain provisions which, through reference in

39、the DM-REP1 MAC layer protocol. The selected method is the remote method, as defined in ISO/IEC 9646-2 6, clause 11. This test method has been selected, because: - this test method implies no specific requirements from the Implementation Under Test (IUT); - - the upper Service Access Point (SAP) of

40、the IUT cannot be directly observed; the variety of the possible TETRA implementations is a serious technical obstacle for the adoption of a different ATM; - this test method places minimum limitations in the realization of conformance testing. The DM-REP1 MAC protocol defines the operation of a DM-

41、REP1 serving two air interfaces, the master and the slave link. To test the repeater operation in some cases both interfaces need to be controlled and observed simultaneously. This implies that two testing methods are used: the remote single-party test method (with one PCO) and the remote multiparty

42、 test method with two PCOs. 4.1 Single PCO testing The remote Single Party test method with a single PCO is illustrated in figure 1. layers Figure 1 : Remote SPyT test method for TETRA DM-REP1 MAC layer 4.1 .I Lower Tester (LT) A LT is located in a remote TETRA test system. It controls and observes

43、the behaviour of the IUT. 4.1.2 Upper Tester (UT) There is no explicit UT in the remote test method, but the DM-REP1 MAC layer and the layers above inside the System Under Test (SUT) are used implicitly for testing the MAC layer. 4.1.3 Test Coordination Procedures (TCP) The implicit send events defi

44、ned by the provider of an implementation in annex B serve the purpose of the TCP. They are used as an input to the IUT communicating with the UT to initiate test events at the DMO MAC layer. ETSI 9 ETSI TS 1 O0 394-4-6 V1.l.l (2000-1 1) 4.1.4 Point of Control and Observation (PCO) All test events at

45、 the PCO carrying service user data are specified in terms of MAC layer PDUs. Only few Abstract Service Primitives (ASPS) are defined for control or observation purposes. The mapping of the MAC PDUs into the physical layer frame structure is left to the test implementation. 4.2 Multiple PCO testing

47、Two LTs: LT1 and LT2 are located in a remote TETRA test system. They observe the behaviour of the IUT. They are controlled and synchronized by the lower tester control function. 4.2.2 Upper Tester (UT) There is no explicit UT in the remote test method, but the layers above inside the System Under Te

48、st (SUT) are used implicitly for testing the DM-REP1 MAC layer. 4.2.3 Test Coordination Procedures (TCP) The implicit send events defined by the provider of an implementation in annex B serve the purpose of the TCP. They are used as an input to the IUT communicating with the UT to initiate test even

49、ts at the MAC protocol layer. 4.2.4 Point of Control and Observation (PCO) The PCOs are located inside the protocol. All test events at the PCOs carrying service user data are specified in terms of MAC PDUs. The mapping of the PDUs to possible physical layer service primitives is left to the test implementation.
